A triangular grid generation and optimization framework for the design of free-form gridshells [PDF]
, 2019 Gridshells have been widely used in various public buildings, and many of them are defined over complex free-form surfaces with complex boundaries. This emphasizes the importance of general grid generation and optimization methods in the initial design ...

A family of H-div-div mixed triangular finite elements for the biharmonic equation
Results in Applied Mathematics, 2022 A family of Pk+22×2-PkH(divdiv)mixed finite elements on triangular grids is constructed for the biharmonic equation. For the H(divdiv)mixed finite element functions, both the stress tensor and its divergence have continuous normal components, σh⋅nand ...

Bijective, Non-Bijective and Semi-Bijective Translations on the Triangular Plane
Mathematics, 2019 The triangular plane is the plane which is tiled by the regular triangular tessellation. The underlying discrete structure, the triangular grid, is not a point lattice. There are two types of triangle pixels. Their midpoints are assigned to them.

Two-Step Colouring of Grid Graphs of Different Types
Моделирование и анализ информационных систем, 2022 In this article, we consider the NP-hard problem of the two-step colouring of a graph. It is required to colour the graph in a given number of colours in a way, when no pair of vertices has the same colour, if these vertices are at a distance of 1 or 2 ...

Effect of boundaries on grid cell patterns
Physical Review Research, 2020 Mammalian grid cells represent spatial locations in the brain via triangular firing patterns that tessellate the environment. They are regarded as the biological substrate for path integration and to provide an efficient code for space.

Word-representability of face subdivisions of triangular grid graphs [PDF]
, 2016 A graph G = (V, E) is word-representable if there exists a word w over the alphabet V such that letters x and y alternate in w if and only if (x, y) ∈ E. A triangular grid graph is a subgraph of a tiling of the plane with equilateral triangles defined by

Digital and automatic design of free-form single-layer grid structures [PDF]
, 2022 Grid shells have been widely used in various long-span public buildings, and many of them are defined over freeform surfaces with complex boundaries. This emphasizes the importance of general and digitalised grid generation and optimization methods in ...
